Abstract

Firewall is a critical technology in protecting enterprise network systems and individual hosts. Firewalls can be implemented through a specific software application or as a dedicated appliance. Depending on the security policies in an organization, several firewall implementation architectures are available, each with its advantages and disadvantages. Therefore, a thorough understanding of firewall technology, its features and limitations, and implementation considerations is very important in the design and implementation of effective firewall architecture in an organization. This chapter covers the life cycle of firewall design, selection, and implementation.
